ANS. 5. The dichotomous key is based on the already known organisms but if a new species will get discovered then automatically it wouldn't be on the dichotomous key. hence, all plant species in the wildlife sanctuary is not found in the D key.
ANS. 6. The developed campus had biodiversity that is common to urban life and on the other hand, wildlife sanctuary had many more organisms than the developed campus.
ANS. 7. The development of an acre of open space in the wildlife sanctuary has greatest impact on species diversity because there is no human interference.

7. In certain species of plants, mutations can cause the electron transport chain connecting PSII to PSI to flip orientation. This change in orientation causes the electron transport chain to become ordered in terms of decreasing electronegativity instead of increasing electronegativity. What portions of photosynthesis will be affected by this change in the orientation of the electron transport chain? Why? 8. A mutation in the genome of a plant prevents proper folding of rubisco. How would this impact the Calvin...

You have identified a new species of flowering plant with red flowers instead of the usual blue flowers. You performed a cross and found that all of the F1 plants had purple flowers. When you self-fertilized these F1 plants, the resulting F2 was: Blue flowers: 1034 Purple flowers: 297 Red flowers: 94 What would the expected numbers be if these phenotypes were due to two alleles with incomplete dominance at a single loci? What if these phenotypes were due to...

4.The article mentions that when prices are low, farmers may have an incentive to plant additional acres. Explain why this does or does not conform with the principle of marginal analysis. Feel free to use an example of how a farmer may choose whether or not to plant an additional acre of corn to explain your answer.

Protected areas aim to safeguard biodiversity, preserve ecosystem services and ensure the persistence of natural heritage [1]. Despite their essential role in conservation, the allocation of resources to cope with an increasing variety of regular activities and unforeseen circumstances remains generally insufficient [2], severely affecting overall effectiveness [3]. Besides, protected areas subjected to international and national agreements must resolve their acquired responsibilities to maintain their legal status [4]. Hence, there is a demand for cost-effective, versatile and practical initiatives to...

We conducted a comprehensive literature search on drones in conservation up to October 2nd 2018, in line with related studies [10,11,35]. All searches were done by the same person in English, mainly using Google Scholar. This was further complemented through reference harvesting, citation tracking, abstracts in conference programs, and author search, using Research Gate and Mendeley (see PRISMA Flowchart in Supplementary Figure S1 Checklist and list of studies reviewed in Table S1). We then removed duplicate and unrelated results. Finally,...
